Ethylene Glycol Distearate
Broad Industrial Utility: Ferrous sulfate heptahydrate finds extensive application across multiple sectors including pigment manufacturing, water treatment, and reduction reactions.
Effective in Water Purification: It serves as an important agent in water treatment systems, aiding in the removal of contaminants and enhancement of overall water quality.
Essential for Pigment Manufacturing: The compound acts as a crucial raw material in producing a variety of pigments, delivering intense coloration and superior finish in end products.
Adaptable Through Dehydration: Subject to dehydration treatment, it can be converted into anhydrous ferrous sulfate, thereby broadening its functional utility across diverse industrial applications.
Upon gradual heating, ferrous sulfate heptahydrate undergoes dehydration, eventually transforming into anhydrous ferrous sulfate. The process of dehydration leads to the removal of the seven water molecules associated with the crystal structure, resulting in the formation of dry ferrous sulfate. Upon controlled heating, ferrous sulfate heptahydrate gradually loses its water of crystallization, converting into the anhydrous form. This dehydration process eliminates the seven molecules of water integrated within its crystalline lattice, leading to the production of dry ferrous sulfate. The compound is widely employed in several industrial sectors, including pigment manufacturing, water treatment, and serving as a reducing agent in chemical reactions.
